SOLVED: (Ubuntu) user permissions

[mjpatey]

I'm running Jellyfin Server on Ubuntu 24.04 with my media files on an external exFAT hard drive, mounted in /media/Media. Jellyfin can see the files, navigate through them, and write new files to the drive.

But I can't copy a new media file to the drive myself, so I need to set up the proper permissions. If I do this:

Code:

chmod -r 750 "/media/Media"

...will that allow both me and Jellyfin to do what we need? It looks like my Jellyfin installation did create a "jellyfin" user, per this line in /etc/passwd:

Code:

jellyfin:x:122:124:Jellyfin default user,,,:/var/lib/jellyfin:/bin/false

I've never gone this deep into this sort of thing, so thanks for any insight!

EDIT: I have read TheDreadPirate's excellent primer, but I'm still having a hard time wrapping my brain around it. All subfolders of the drive are currently set to:

Code:

drwxr-xr-x
